Title: The Phantom Sheet
The rain in Sarnia battered the corrugated metal roof of the archive shed, a rhythmic drumming that usually put Elias to sleep. But tonight, the old chemical plant’s records keeper was wide awake, staring at a three-ring binder that shouldn't exist.
Elias was a man of routine. He liked his chemicals labeled, his hazards identified, and his paperwork in triplicate. For thirty years, he had managed the Safety Data Sheets (SDS) for the refinery. He knew the sting of Hydrochloric Acid and the sweet, sickly smell of Benzene. But he had never heard of NALCO 73385.
The file had turned up during a digital migration. While scanning boxes of legacy documents from the 1980s, his scanner had choked on a laminated, yellowed sheet. It wasn't the standard government-issued format. It was typed on a typewriter, the letters slightly askew, bearing the old Nalco logo.
Product Name: NALCO 73385 Use: Corrosion Inhibitor / Catalyst Scrubber (Experimental) Manufacturer: Nalco Chemical Company (Classified Division)
Elias frowned. He pulled up the modern Nalco database. He searched for 73385. Result: No matching records.
He tried the OSHA archives. Nothing.
He looked back at the laminated sheet. The first four sections were standard—boiling point, specific gravity—but Section 2, Hazards Identification, was bizarre.
Appearance: Clear, viscous liquid. Odor: Odorless. Primary Routes of Entry: Inhalation, Skin. DO NOT INGEST. Health Hazards: Acute exposure results in temporary sensory displacement. Chronic exposure results in temporal displacement.
Elias wiped his glasses. "Temporal displacement?" he muttered. "Is this a joke? Some outdated sci-fi reference?"
He turned the page. Section 6: Accidental Release Measures.
Spill Response: Evacuate area immediately. Do not look directly at the spill. Deploy liquid nitrogen containment. Under no circumstances should the spill be allowed to reach a temperature of 20°C or higher.
Elias felt a chill that had nothing to do with the drafty shed. He looked at the bottom of the sheet. The date was smudged, but he could make out the year: 1978.
He picked up his desk phone, intending to call his supervisor, but the line was dead. Static crackled on the other end, rhythmic and pulsing. He hung up.
He went back to the binder. He needed to find the First Aid measures (Section 4). If this stuff was dangerous, he needed to know how to treat it. But the page for Section 4 was torn out. A jagged edge of paper was all that remained.
Clang.
The sound came from the loading dock. It was the heavy, metallic groan of a drum being shifted.
Elias grabbed his flashlight. "Hello?" he called out. "The yard is closed."
He stepped out of the office and into the labyrinth of racking systems. The air smelled of wet concrete and old oil. He swept his beam across the aisles.
Thud. Thud. Thud.
It sounded like a heartbeat. Or a slow, heavy drum.
He rounded the corner of Aisle C, where the "Unknown/Disposal Pending" inventory was kept. His light caught a streak of wetness on the floor. It wasn't water. It was a shimmering, viscous liquid, sitting perfectly still despite the slanted floor. It looked like liquid glass.
Elias stopped. The temperature in the aisle was dropping. His breath puffed out in white clouds. He looked at the MSDS sheet still clutched in his left hand.
Deploy liquid nitrogen containment.
He backed away slowly. The liquid on the floor began to vibrate. It didn't spread out; it pooled together, defying gravity, rising into a trembling column.
He remembered the line: Do not look directly at the spill.
He squeezed his eyes shut and turned to run. He slammed into a shelving unit, his panic rising. The air around him was warping; it felt thick, like wading through water. He heard a sound—not a voice, but a thought that inserted itself directly into his mind.
Classification: Organic. Status: Disturbed.
"Get away!" Elias shouted, stumbling toward the fire station pull station on the wall.
He reached for the lever, but his hand passed through it. The metal was transparent, ghostly. He looked at his own arm. It was flickering, phasing in and out of solidity.
He looked back at the spill. The column had taken shape. It wasn't a monster; it was a window. Through the shimmering liquid, he saw the shed, but it was different. It was new. The floor was polished, the lights were fluorescent and humming, and a man in a 1970
